I also use GYO & have had 5 successful orders with them in about 6mths time. No credit card issues, they are very good about staying in touch w/info about your order-you get an email conformation when your order is processed-another when it ships-then another with the tracking info, they have live chat on their website & I've used it several times to ask questions & get instant answers, they usually ship in a day or 2 but right now-the busiest time of the year-they're taking about 5 days to ship, I always get my order on the East Coast around 2 weeks from ordering , love their packaging, the shipping is reasonable, the freebies are good & you get discounts on every order. Awesome seed selection & quality.
Their sister company-Bonza-has a bad reputation & I wouldn't order a used hand towel from them but apparently they are run separately by 2 completely different groups of people. Someone on here had a lot of problems dealing with Bonza but I don't remember who. I had 2 seeds not pop from GYO one time & it ended up being my fault. I let them get too dry.
They have several ways to communicate with them...email, message them from your account on the website, or live chat, & they keep up with any communications by calling it a "ticket" & issuing a "ticket #"...like an invoice. So if you get an email talking about ticket # xxx don't be confused by it...it just gives them/you a reference # to identify that particular conversation in the future if needed. It may sound like you ran a red light lol but it's a good thing. Ticket=conversation.They really are great & very easy to deal with.
